The precision-engineered shape of the femoral stem implant is crucial to
obtaining long-term, pain-free results for the patient. The hip replacement
implant is going to become part of the patient?s body, so achieving an optimal
fit within the femur is key to a successful outcome. Surgeons refer to this as
?fixation.?
There are two ways surgeons can affix the hip implant to the patient?s bone.
One way is to use acrylic bone cement, which helps to affix the stem to the
femur.
The cementless alternatives sometimes use a porous coating, which helps
provide for biological attachment that secures the implant. As an example,
three-dimensional beaded coating creates a surface for the patient?s tissue to
attach, creating a strong bond with the patient?s own natural tissue and the
implant.
